Construction insolvencies nearly tripled typical monthly levels in August, hitting 868 against a running average closer to 300 over the past year — with residential builders bearing the brunt, according to CreditorWatch's latest Business Risk Index.
The spike lands just as a data centre investment pipeline worth more than $150 billion to 2030 begins reshaping demand across the construction sector. New South Wales and Victoria account for roughly 91% of that future pipeline, according to CommBank estimates cited in the report, concentrating demand for land and skilled labour in the country's busiest construction markets.
While commercial builders, electrical contractors, and specialist engineering firms stand to benefit from years of high-value data centre work, CreditorWatch cautioned the same boom could pull scarce trades and materials away from housing at a time residential builders can least absorb the added cost.
HIA recently raised concerns that fast-track planning mechanisms mean a data centre could clear approvals faster than a single home, with growth corridors already experiencing housing delays tied to infrastructure constraints.
That strain is already visible in the numbers: construction's 60-plus-day payment arrears rate sits at 6.5%, ranking fourth among the 18 sectors CreditorWatch monitors, and up 13.3% over the year. Residential building carries the industry's third-highest trade payment default rate at 1.94% and its second-highest tax default rate at 1.58%.
CreditorWatch chief executive Patrick Coghlan (pictured) said the figures highlighted a gap between where investment is flowing and an industry's underlying capacity to deliver it.
"Approvals tell you where the money wants to go," Coghlan said.
CreditorWatch also pointed to rising fuel and materials costs as a factor likely to push both the Reserve Bank and the US Federal Reserve toward tighter monetary policy at their September meetings. The RBA held the cash rate at 4.35% in August, with its next call due at the RBA's scheduled 29 September policy meeting — inflation eased slightly to 3.5% in the year to July, though the RBA's preferred trimmed mean measure held at 3.6%, still above its 2%–3% target.
CreditorWatch chief economist Ivan Colhoun said businesses were already contending with a difficult cost environment.
"Businesses have already been experiencing elevated rates of cost increase for many years," Colhoun said, adding that a further lift in the cash rate would add to pressure on highly leveraged firms and those exposed to discretionary consumer spending.
For brokers, the data signals growing divergence in credit risk across the construction sector — with implications for how residential development and construction lending are assessed heading into the final quarter of 2026.
